Re: Million access to GWT Appl ??
You know that cows (and deer too) chew their cud. Cows have a secondary stomach, so it could store whatever grass it has chewed off the field in the 2ndary stomach. Then it could regurgitate the stored cud and chew on it afterwards. Your question is akin to saying that you read an article that says that the delivery of food (cows like alfalfa, I'm told) to cows is not efficient when there are more than a million cows in a dairy farm, the reason being cows chew their cud. What has cows chewing their cud got to do with the efficiency of delivery of food to cows. It is the fault of the delivery system and has nothing to do with whether a cow chews its cud. The efficiency of delivery is the same whether there are a million cows or a million kangaroos. Obviously, the article you read is erroneous and/or its author has a huge grudge against Google. Likewise, GWT allowing a browser to chew on its cud does not dictate the efficiency of the data delivery system. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

StackLayoutPanel within a ScrollPanel
I want a StackLayoutPanel with a bar for each letter of the alphabet. The idea is that Contacts will be organised within the appropriate bar. All works fine, except when I try to put my SLP within a ScrollPanel so that I can have a shorter window. When I do this, I see the A bar only, the rest of the SP is blank. If I look at the DOM, I can see the other bars with descending positive values of style-bottom. Thus they are rendering with Z immediately above the A (and outside my viewable window), Y above Z and so on. Any ideas how to make SLP and SP play nice together? best Roy -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Unsinking mouse over/out/move events for a CellList/Tree/Table
Summary: in a CellList I want to sink the ONCLICK and ONCONTEXTMENU events to be handled by my Cell's onBrowserEvent method, but I don't want any mouse over/out/move events, but cannot seem to unsink them. In 2.1 M1 we have CellList. If you look at the constructor of CellList you'll see on line 139 sinkEvents(Event.ONCLICK | Event.ONCHANGE | Event.MOUSEEVENTS); So the CellList is presuming that these are the events that we're interested in. Now I have created my own concrete implementation of an AbstractCell. Other implementations are TextCell, ButtonCell, CheckboxCell, etc. So I have followed those as examples, but have created my own Cell implementation. One of the methods that can be implemented is: public abstract Object onBrowserEvent(Element parent, C value, Object viewData, NativeEvent event, ValueUpdaterC valueUpdater); ... and in that method I am interested in a Click event and a Context menu event. I notice that my CPU usage peaks at 50ish% when I move my mouse around. Sure enough GWT is picking up all the mouse over, mouse out, mouse move events as well. AND I'm not getting my Context menu event (because I haven't explicitly sunk it yet). So in my UI class that keeps an instance of this CellList, in the constructor I have: myCellList.sinkEvents(Event.ONCONTEXTMENU); myCellList.unsinkEvents(Event.MOUSEEVENTS); ... so now I am getting my Context menu event, but I am still getting a flood of mouse events as I wiggle my mouse over the Cells in the CellList. I have tried explicitly unsinking Event.ONMOUSEOVER et al. but that has no effect either. Either this is a bug, or more likely I am unsinking the event on the wrong element or unsinking in the wrong order, or I am missing something altogether.

FYI: Element .getTagName() returns uppercase tag names, like DIV, LABEL, SPAN
Using 2.1 M1 I noticed that Element has the method hasTagName, which
looks like this:
public final boolean hasTagName(String tagName) {
assert tagName != null : tagName must not be null;
return tagName.equals(getTagName());
}
Almost synonymous with this:
div.equals(element.getTagName())
However one gotcha got me, assume element is a div:
div.equals(element.getTagName()) --- returns false :-(
DIV.equals(element.getTagName())--- returns true :-)
Likewise:
element.hasTagName(div)--- returns false :-(
element.hasTagName(DIV)--- returns true :-)
Obviously Java's String .equals() method is case sensitive. But how
would we know that element.getTagName returns uppercase or otherwise?
Here is the method at is stands in 2.1 M1:
/**
* Gets the element's full tag name, including the namespace-prefix
if
* present.
*
* @return the element's tag name
*/
public final String getTagName() {
return DOMImpl.impl.getTagName(this);
}

Re: Data Presentation Widgets Help
I got started by using antony.trupe's examples given in: http://stackoverflow.com/questions/2891803/how-to-use-gwt-2-1-data-presentation-widgets/2944454#2944454 It doesn't have a CellTree example, and since my project doesn't include a Tree I haven't delved into that yet. I needed something that was like a Table but with more flexibility, so I've ended up just using a CellList and then doing quite a bit of rendering in the render() override of the AbstractCell class. So basically I have a CellList that is a list of MyCustomCell, and in there I have learned all that I need by looking at other implementations of AbstractCell, such as TextCell, ButtonCell, etc. On May 21, 5:15 am, licht...@gmail.com licht...@gmail.com wrote: Anyone know where to find the sources, examples, docs to the new Data Presentation Widgets? -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Is your database situated on the server-side or on the client-side ?

Re: Why appear OPTIONS instead of POST in my RPC calls?
Thanks for your comment, it helped me a lot. Indeed that's the problem.
I guess the next step is to create a good response so the RPC works. Or is
there any better solution? (I can't avoid the cross-site situation)

res.addHeader(Connection, Keep-Alive);
res.addHeader(Keep-Alive, 115);
res.addHeader(Access-Control-Allow-Origin,
req.getHeader(Origin));
res.addHeader(x-gwt-permutation, GWT.getPermutationStrongName());
res.addHeader(x-gwt-module-base,
http://localhost:8084/AnalisiHeuristic/cat.udl.griho.AnalisiHeuristic.Main/
);
}

approach? :(

Re: Unsinking mouse over/out/move events for a CellList/Tree/Table
Thanks Thomas,
Test and works as suggested. The class owning my CellList extends
Composite and I now have overridden the onLoad method like this:
@Override
protected void onLoad() {
myCellListView.unsinkEvents(Event.MOUSEEVENTS);
}
... and no longer are the mouse over/out/move events flooding into my
console. Interesting I still get a CPU spike when I wiggle my mouse,
but I am in hosted mode, could this have something to do with it?
Could it be that when I compile to javascript these mouse events are
genuinely ignored and have no processing overhead?
It's not a biggie, it's just that I am rendering a non-trivial view of
data in my CellList and performance is essential.

I've created a new type of Cell that i've named MouseOverCell where I
catch the native event 'mouseover' and than call an abstract method.
So when you add this cell to your table:
addSortColumn(XX, new MouseOverCell() {

public void onMouseOver() {
Window.alert(ON MOUSE OVER);
}
}, new GetValueOperatore, String() {
public String getValue(Operatore object) {

Grid - controlling pixel sizes
Hello,
I would like to build a Grid (to represent a chess board) with
predictable pixel sizes.
For this I need to know:
Given a single cell has pixel sizes (x, y), what's the pixel size of
the whole grid?
How can I compute this?
In this context I tried to set every cell to an exact pixel size:
for (int y = 0;y 8;y++)
for (int x = 0;x 8;x++)
{
grd.getCellFormatter().setWidth(y,x,50px);
grd.getCellFormatter().setHeight(y,x,50px);
}
But I found out that the first inner statement (for the cell's width)
is completely ignored. Whatever I enter for the width, it does not
change anything. The heigth ist set correctly. As a consequence, I
cannot really controll the cell's pixel sizes. What's that?
The code for my component is shown below.
Thank you
Magnus
-
package chess.client;
import com.google.gwt.user.client.*;
import com.google.gwt.user.client.ui.*;
public class Board extends AbsolutePanel
{
private Grid grd = new Grid (8,8);
public Board ()
{
super ();
add(grd);
init ();
}
private void init ()
{
setPixelSize (400+2,400+2);
grd.setBorderWidth(1);
grd.setCellPadding(0);
grd.setCellSpacing(0);
grd.setPixelSize(402,402);
for (int y = 0;y 8;y++)
for (int x = 0;x 8;x++)
{
grd.getCellFormatter().setWidth(y,x,111px);
grd.getCellFormatter().setHeight(y,x,49px);
}

Pass a method as parameter in GWT
Hi.
Im building a logic here that a class A instantiate a object of
another class B. B has a specified clickHandler that does a animation.
I want that the class A can pass a method to the class B as a
parameter to do the animation and some extra stuff that I wanna do in
the class A.
So I was thinking in something like that:
class A
Button trigger = new Button();
trigger.addClickHandler(new ClickHandler(){
//doStuff
callBack();
}
class B
A a = new A();
a.setCallBack(doThis());
public void doThis(){
Window.alert(test);
}
How can I do that in GWT?
Thanks for the attention
Cheers

Re: server side entry point to open/close database?
Hello, after your post I would open/close my db within each service call. If I would do it with a pool, I would need 2 entry points, one to open the pool and one to close it. If I would go this way, would these entry point exist (is there a deinit)? Thanks Magnus On 20 Jun., 15:58, roji rojan...@gmail.com wrote: Hi Magnus. Your server-side service implementation is a class that extends GWT's RemoteServiceServlet, which itself extends the Servlet interface. If you need to perform once-only initialization, you can do so by overriding the init() method in your class. Note, however, that init() is probably a bad place to open database connections, as your backend will be accessed concurrently by many users and multiple database connections are needed. You should probably either open and close database connections inside the RPC service calls themselves (using a database connection pool behind the scenes), or in some scenarios store some resources in the user's HTTP session (acquired by calling this.getThreadLocalRequest().getSession()). If you need more help, can you send more details about your application?

Re: UIBinder Benefits?
Hi,
On Jun 22, 3:36 pm, Andrew Hughes ahhug...@gmail.com wrote:
Almost all of the problem's listed below are bad advice and I suggest you
disregard them.
Do you, or others, have any valid arguments (opinions are no valid
arguments)
I am not going to do things the wrong or the poor way just because
most people are doing so.
The main problem I have with UiBinder is that when you try and use it with
the MVP architecture best practice, you have to boilerplate all the
parent/child (view) widget's. Which means you'll see a lot of.
I am explaining the long story about my lessons I learned.
The problem with any pure declarative language is that you reached the
dead end of separation.
Either a dedicated aspect of separation is build in, or you are lost.
There is always a tradeof where declarative languages will become more
complex than an imperative one.
UiBuilder is a pure declarative language.
Let us look at CSS as a simple pure declarative language for example.
Consider there are two aspects/concern defining an value.
aspect 1) general theming. you want a certain padding
aspect 2) behaviour, you want to simulate a pressed state. Therefore
you need to change padding depending on the state
With a imperative language (java) you would just combine/add both
aspects.
With a language like css either this is supported or not. In css it is
not, bad luck.
(CSS3 supports a little imperativity with calc, but only FF is
supporting this somehow)
And the pure declarative language CSS 2.1 still fails to support some
simpliest common needs.
Remember all the time the topic of centering widget is coming up.
UiBinder fails the same way. It limits always your capabilities as a
developer. Either a concept is explicitly supported, or you are lost.
There are other ways to be more declarative. One way is to use fluent
interfaces. Than you use both declarative and imperative approaches,
and can switched to the one which is more appropriate
the way I am currently using is to define interfaces and use
generators.
The input looks like the interfaces at the end of this mail.
It defines a dialog with 2 subdialog.
To create you need just.
LogonDialog logon = GWT.create(LogonDialog.class);
..
logon.layout();
logon.setI18N (..Constants);
Accessing is a easy as
String text = logon.eingabe.eMail().getText()
Let us compare this approach with UiBinder
generator: only one annotated interface for deferred binding
UiBinder: class and UiBinder.XML with XMTL, CSS and WidgetsTags
generator: layout automatically according css-style and annotations
UiBinder: dialog designer does it manually.
generator: i18n constant change at any time
UiBinder: i18n per compilation
generator: automatic labeling, yes
UiBinder: automatic labeling, no
generator: styles based theming
UiBinder: styles based on accident
generator: widgets, any with a default constructor
UiBinder: some widgets
generator: consistent layout is automatically asured
UiBinder: layout by accident/capability of the designer
generator: debugging: yes, pure java
UiBinder: no chance
Open questions with UiBinder
* how to deal when the themes
* how to use it a input for further code generation (I think no way)
Capabilities with generator approach
* rules are in the generator, one place
* control combined widgets (text + label for example making both
enable/disable/hidden)
* input is usable for further code generation
Ideas
* generate controller code, too (input DialogInterface and an
interface defining a domain/app/session object)
* generate request code, too
* generate client cache code, too
* ...
UiBinder is for the one how like to stay in a death end.
When you want to generate boiler plate code,
you need to get rid of UiBinder.

How to make a TabBar with images on the tabs (GWT 2.0)
As a GWT newbie, I struggled with placing images on TabLayoutPanel (or
DecoratedTabPanel?) tabs in place of text labels. The solution is
elegant and VERY simple.
TabLayoutPanel tabPanel = new TabLayoutPanel( 8.5,
com.google.gwt.dom.client.Style.Unit.EM );
VerticalPanel p1= new VerticalPanel();
p1.add( someContent ); // This is the content of the stuff
(view)
that a tab control selects.
tabPanel.add( p1, new Image( images/firstTagImg.png ) ); //
The
second argument centers a image on the tab control.
// Do NOT use RootPanel.get() with LayoutPanels.
RootLayoutPanel.get().add( tabPanel );
Note about file locations:
References like images/firstTagImg.png point to a GWT application's
war/images folder. I don't know if the GWT Eclipse plugin will copy
such resources from (say) the application's src or src/client folder
(hosted server), so I manually copy them or explicitly make ant do so.
To identify the selected tab by its background, use styles like these:
.gwt-TabLayoutPanelTabs .gwt-TabLayoutPanelTab {
background-color: blue;
}
.gwt-TabLayoutPanelTabs .gwt-TabLayoutPanelTab-selected {
background-color: green;
}
I put those definitions in war/WEB-INF/the project name.css .

Code after History.fireCurrentHistoryState() will execute any more?
hi,
I have an MVP app, on which i'm showing different views on the same
container as per the history token. So one of my view has a context
checking logic, that checks whether the logged in cookie is there or
not. If no cookie, I need to redirect to the login view by changing
the history token. So I wrote a method EnsureUserLoggedin() which will
check the cookie; if cookie not found, the method will add new history
token login and my global history change handler will do the rest.
I'm consuming that method like the following.
{
EnsureUserLoggedin();
Do_my_work();
---;
---;
}
I fear whether this can cause any memory leak? Will this?
If so should i write like the following
{
if(UserLoggedin()) {
Do_my_work();
---;
---;
}
else{
History.newItem(login);
}
}
or you have any other suggestions on it?

Re: GWT Application does not work in IE8 at all?
Hi,
I found your initial post on stackoverflow, and came here hoping for
answers...
I have the exact same problem you have, except it's under IE7. I have
no problem under IE8.
For me, the error comes from:
function entry0(jsFunction, thisObj, arguments_0){
var initialEntry;
initialEntry = entryDepth++ == 0;
try {
return jsFunction.apply(thisObj, arguments_0);
}
finally {
initialEntry $flushFinallyCommands(($clinit_15() , INSTANCE));
--entryDepth;
}
}
If anyone has an idea about what part of the GWT can generate that
kind of code, it would help me find a work around more quickly.

When I locate that line in the generated file (this was all done with

the finally is at:

The problem is that this is not code generated from my client side
java - it seems to be GWT's own generated code.
As a test I added an empty catch block - that now stops Internet
Explorer from complaining but still doesn't load my application up at
all. All that loads is the surrounding html and images and a blank

Hiding fully qualified class name sent to the browser
Hi, Would it be possible to obfuscate the fully qualified class name which is visible at the browser if you use firebug?. I would like to see it as a.b.c.d instead com.mycompany.myproduct.mypackage.MyClassName. Also I do not use the same domain object as model but use Lists and Maps to send data to browser. thanks! -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Is this the correct way to add an Widget directly to DOM ?
Heres my example (a custom widget):
public class TestWidget extends Composite {
private static TestWidgetUiBinder uiBinder = GWT
.create(TestWidgetUiBinder.class);
interface TestWidgetUiBinder extends UiBinderWidget, TestWidget {
}
@UiField
Button button;
public TestWidget(String firstName) {
initWidget(uiBinder.createAndBindUi(this));
button.setText(firstName);
super.onAttach();
}
@UiHandler(button)
void onClick(ClickEvent e) {
Window.alert(Hello!);
}
}
And here the code to add the Widget to a Panel:
TestWidget testWidget = new TestWidget(myTestWidget);
RootPanel.getBodyElement().appendChild(testWidget.getElement());
mainPanel.getElement().appendChild(testWidget.getElement());
I know that it is possible to add an Widget directly to an RootPanel
like this:
RootPanel.get(myId).add(testWidget );
However lets say i want to add widgets directly to the DOM. I don't
really understand why i have to call super.onAattch(); to get my
ClickEvent to work. If i don't execute that line it won't fire. I'm
not sure if this is the right way maybe somebody can give me more
information.

Re: GWT Application does not work in IE8 at all?
I have exactly the same error, except that it happens in IE7. The
application runs fine in IE8. The application is built with GWT 2.0.3.
For the record, the faulty generated code is:
function entry0(jsFunction, thisObj, arguments_0){
var initialEntry;
initialEntry = entryDepth++ == 0;
try {
return jsFunction.apply(thisObj, arguments_0);
}
finally {
initialEntry $flushFinallyCommands(($clinit_15() , INSTANCE));
--entryDepth;
}
}
I need to find a work around, so does anyone know what part of the GWT
generates this code?

When I locate that line in the generated file (this was all done with

the finally is at:

The problem is that this is not code generated from my client side
java - it seems to be GWT's own generated code.
As a test I added an empty catch block - that now stops Internet
Explorer from complaining but still doesn't load my application up at
all. All that loads is the surrounding html and images and a blank
space where my app should be.
Has anyone experienced this before? Any ideas on how to tackle this?

Re: Java Preferences API impl. for GWT
amos schrieb: is there any suitable implementation of Java Preferences API for GWT? Or at least some thought about it? I mean mainly considering client server asynchronous nature of GWT and what could be possible storage engine for this kind of service. I know there is Cookies class, but it's bound to a particular browser, but preferences could be used from any browser on any computer (after user logs in of course). Any browser can be done by a Flash Cookie that is shared between the different browsers AfAIR but if it should work for any com- puter you have to store it on the server side and send it to the client (after the login would be best). That way you don't have to cope with the situation that there are more than one users at a specific machine.

how can I start a HttpServlet in an Eclipse GWT project?
I'm using GWT 2.0 with Eclipse Galileo (3.5). Currently the project works fine, but it's all client side interaction at the moment. I want to use HTTP as the data transfer method, because that's what will be used in production, together with JSON. I want a HttpServet for testing in my Eclipse project because of Single Origin Policy. Basically I took the Greeting example and replaced the GreetingServiceImpl servlet with mine that extends HttpServlet. I edited the names in web.xml.

How to use one service from several GWT-Apps
Hi, I'm currently trying to add some printing functions to a map-software. If the user hits the print-button a new browser-window, which's dimensions fit to a normal sheet of paper, is opened. As the user usually wants to print stuff like a route or so the new window needs to use the same services the main-app does. What I already tried: First I did the printing stuff on its own and tried to merge the projects (map and print). There where some problems because of the web.xml. Then I added another print.html to the map-root-dir and tried to merge the source directly in one project. In this scenario the onModuleLoad()-method of the print.html wasnt fired. Is there a way to let the print-app use its parents-apps services? I'd really like to avoid to have the code twice on my server ... thanks for any advise! tom -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: UIBinder Benefits?
Looking at your annotation, I find that I have to learn yet another language. I mean learning the annotation style as a language.

For the many many years doing distributed computing in industrial environment - I find the unfortunate situation that data come in many formats. There are log sheets that each vendor equipment invented with their own respective formats. Frequently, the same equipment maker willy-nilly comes out with a slight variation just because they have a new line of models. Some are text, some are XML. if you do not strive to be familiar with XML, you don't get to work. So, every time I need to write a data loader for a piece of equipment, should I have complained to management - I have to learn another language, sir/maam? Moreover, databases I encountered are of differing schemata of course. Getting familiarized with an XML schema is similar to encountering yet another database schema. I am personally guilty of inventing more database and XML schemata (the plural for schema is schemata, http://h2g2java.blessedgeek.com/2010/03/data-is-already-plural.html) and adding to the plethora of new languages people who worked with me had to learn. For those of us who've had the misfortune of having to frequently work with deciphering new XML and database schemata, which in your sense - frequently having to learn new languages, UiBinder comes as natural as mother tongue. So my condolences that you find UiBinder difficult for you due to your less exposure to XML. It is indeed an unfortunate situation that the people who came out with UiBinder did not take into consideration that not all people are familiar with XML or are resonant to data schemata.

Im building a logic here that a class A instantiate a object of

I want that the class A can pass a method to the class B as a
parameter to do the animation and some extra stuff that I wanna do in
the class A.
So I was thinking in something like that:
class A
Button trigger = new Button();
trigger.addClickHandler(new ClickHandler(){
//doStuff
callBack();
}
class B
A a = new A();
a.setCallBack(doThis());
public void doThis(){

How can I do that in GWT?

Re: Disable the default contextmenu in richtext editor
You are on the right track with these: event.preventDefault(); event.stopPropagation(); But firstly, are you clear about the difference between a Click event and Event.ONCONTEXTMENU? You may be trying to suppress the click event, but you really need to 1) sink the context menu event, and 2) prevent default actions... myElement.sinkEvents(Event.ONCONTEXTMENU) ... followed by... event.preventDefault(); event.stopPropagation(); (this might not even be necessary) ... should do it. wild speculation If not, then another idea is that the rich text area is probably using an IFrame, am I right? If so it may be the case that the events belonging to *this* window, and the events belonging to the IFrame are handled in different places. /wild speculation On Jun 22, 4:56 pm, shruti shrutiredd...@gmail.com wrote: Hi, I have created my own popup menu, which I want to display in RichTextArea, and it is appearing with right mouse click. my problem is that default broswer's context menu does also appear along with my menu. is there any resolution for this?

Re: Is this the correct way to add an Widget directly to DOM ?
Your question seems a little confusing, but your idea is not quite
right. Firstly you shouldn't have to call super.onAttach(), the real
problem is you are effectively bypassing GWT's widget/event system by
trying to get the widget's element and attach it directly. In effect
you're mixing GWT and Javascipt and it's not being done correctly.
By adding to the DOM I think you mean add to the body element,
rather than adding to a particular element.
You give the example:
RootPanel.get(myId).add(testWidget );
... but if you want to add to the body, just do:
RootPanel.get().add(testWidget );
... and get rid of that super.onAttach()

Button button;
public TestWidget(String firstName) {

button.setText(firstName);

@UiHandler(button)

And here the code to add the Widget to a Panel:
TestWidget testWidget = new TestWidget(myTestWidget);
RootPanel.getBodyElement().appendChild(testWidget.getElement());
mainPanel.getElement().appendChild(testWidget.getElement());
I know that it is possible to add an Widget directly to an RootPanel
like this:
RootPanel.get(myId).add(testWidget );
However lets say i want to add widgets directly to the DOM. I don't
really understand why i have to call super.onAattch(); to get my
ClickEvent to work. If i don't execute that line it won't fire. I'm
not sure if this is the right way maybe somebody can give me more
information.

Re: How to use one service from several GWT-Apps
service? Printing thro web service that all/any window could call with a single url? Why would you need to duplicate code when you can call it with a single url? Or did you mean you have a specialised GWT window written to handle printing and you wish to route all printing to that GWT window? And you wish to deal with the occasionally asked question of how to perform inter-frame communication for GWT? I don't remember now, but there is a google code project to expose GWT objects to javascript. Coupled with GWT Dictionary API, I wonder if that will help. Of course, you do realise that for two frames to communicate, they should have the same root Window parentage so that one frame could refer to another thro the frame hierarchy.

One Service, multiple users
I have a service that instantiates and keeps state (variables in the back end that is controlled by the service) until the user logs out. What happens exactly when two users access my GWT service; will there be one service instance for each user or will one be shared between them? I try to figure out if my service is actually multi-user or not... Ralf -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: RPC call does not work after upgrading to Safari 5
After further research on the web and directing me to review my server's logs I believe my problem may be due to my app still being run as a gwt 1.4. If so, are there any options other than upgrading the app to a newer gwt version? Below is from my Tomcat server log: SEVERE: Exception while dispatching incoming RPC call javax.servlet.ServletException: Content-Type must be 'text/plain' with 'charset=utf-8' (or unspecified charset) at com.google.gwt.user.server.rpc.RemoteServiceServlet.readPayloadAsUtf8(RemoteServiceServlet.java: 119) at com.google.gwt.user.server.rpc.RemoteServiceServlet.doPost(RemoteServiceServlet.java: 178) ...

MVP with EventBus question
Working with the MVP pattern, or more like the VP pattern at this
point, I have:
MainPagePresenter
MainPageView
WidgetA
WidgetB
... so imagine that WidgetA and WidgetB will be attached to
MainPageView.
Using Gin I have an EventBus injected into the MainPagePresenter. I
can then add click handlers that place an event on the EventBus from
within my MainPagePresenter. This might look like:
getMainPageView().getSendButton().addClickHandler(new ClickHandler(){
public void onClick(ClickEvent event) {
eventBus.fireEvent(new SendEvent());
}
}
But now let's say that WidgetA and WidgetB actually have quite a few
user interactions, you'll end up with a lot of methods that look like
the one above sitting in your Presenter class.
1. Is this correct?
Or
2. should the Presenter hand the reference to the EventBus through to
its View, who may even hand it through to the Widgets so that they can
talk directly to the EventBus?
If the second option is the better option from an architecture/
separation of concerns point of view, then what is the best way to
hand the reference over to the View in such a way that keeps the
coupling between Presenter and View as loose as possible?
Note, currently my Presenter defines a View interface which my View
implements, so the coupling is loose but based upon this interface.

As per the JavaDoc of the deprecated methods: use another widget,
probably a Label in this case, with the appropriate styling to make it
look like a link if that's what you want.

Re: How to use one service from several GWT-Apps
sorry i meant service. i try to explain the problem more precisely: i got a map. users can, for example, use the app to calculate a route- advise. if the user did so he may want to print the route. but the map is nearly fullscreen, so if he justs prints it like that it looks pretty bad. so what i do is to open a new browser window with a smaller map. and now in this new window the route must be newly calculated, because you cant give a java object to the new window, right? what i want now is that the print page uses the routing servlet of the main app. what i dont want is that the print page needs all the same server code again. but i dont get it working. because if i merge the projects the web.xmls clash. thanks a lot! tom On 23 Jun., 21:47, Blessed Geek blessedg...@gmail.com wrote: service?

Re: MVP with EventBus question
To answer my own question:
1. Gin can be used to inject the EventBus into the View as well as the
Presenter, so now our View has a reference to the EventBus
2. In order to give the EventBus to the Widgets owned by the View
those Widgets will require a constructor argument which will be the
EventBus instance. UiBinder will fail if it doesn't find a default
constructor, except that they have provided some nice work arounds.
The appropriate workaround in this case is to provide a widget
factory. Notice the use of @UiFactory in the example below:
public class UserDashboard extends Composite {
interface MyUiBinder extends UiBinderWidget, UserDashboard;
private static final MyUiBinder uiBinder =
GWT.create(MyUiBinder.class);
private final String[] teamNames;
public UserDashboard(String... teamNames) {
this.teamNames = teamNames;
initWidget(uiBinder.createAndBindUi(this));
}
/** Used by MyUiBinder to instantiate CricketScores */
@UiFactory CricketScores makeCricketScores() { // method name is
insignificant
return new CricketScores(teamNames);
}

RE: GWT 2.1.0 M1 and Roo development lifecycle. What would you do?
Think the whole point of having Roo + GWT is to easily generate pumping codes like getters and settings and data transfer objects etc without too much hand coding. I am not an expert on GWT nor Roo, but so far it looks like it still need some work to iron out some strange issue, like the generated scaffolding is not as robust as Grails and it doesn't run under chrome but only runs on firefox. But as far as the concept goes and I am experimenting it hoping to recommend it to our next project to use GWT + Roo. I love Roo keep monitor the state of the project and generate mechanical code on the side away from the src thru aspect so I don't have to do it and it won't mess my src up. It doesn't bother me much that it’s a code generator. Grails is actually a runtime code generator as well and it is very popular, albeit too much black magic and no decent tool support. I say as long as it doesn't mess with my src, I am good with it.

I wrote some programs when in college with the AspectJ (the base of the Spring Roo) and it was very nice to have custom aspects around my java classes.

Anyway, i uploade some samples using my code template to generate some GwtEvents (the base for the MVP cool development in GWT).

However, I made this workaround and it's ok for me at the moment:
public void setEnabled (boolean e)
{
IteratorWidget itr = grd.iterator (); // grd is a FlexTable which
contains my form controls
while (itr.hasNext ())
{
Widget w = itr.next ();
if (w instanceof TextBox)
{
TextBox t = (TextBox) w;
t.setEnabled (e);
}
if (w instanceof PasswordTextBox)
{
PasswordTextBox t = (PasswordTextBox) w;
t.setEnabled (e);
}
...
}

Re: One Service, multiple users
GWT Services are nothing but HttpServlets. And single instance of servlet can serve multiple requests, which can be from different users. To store attributes per user, use HttpSession instead of variables in GWT Service. HttpSession can be retrieved from GWT service by calling getThreadLocalRequest().getSession(). Prakash M.

Re: server side entry point to open/close database?
Hi Magnus.
The standard enterprisey way to do this, would be to use a
javax.sql.DataSource as a representation of your database. Your
RemoteServiceServlet would look up this object in JNDI at
initialization time, and create connections by calling
getConnection() on it each time a user connect.
The actual connection pool would be managed outside your application.
For example, when you define a DataSource resource in Tomcat, an
Apache connection pool (DBCP) is created. This way, when your
application asks for a new connection, it will be transparently
reusing pooled connections.
Example servlet:
class MyServlet
extends RemoteServiceServlet
implements MyServletService
{
@Resource(name=jdbc/db) // This makes your servlet container
inject the JNDI resource found under jdbc/db
private DataSource db;
public void myGwtMethod() {
Connection conn = db.getConnection();
}
...
}
If you're using Tomcat, take a look here for how to manage DataSource
resources:
http://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.html.
To answer your specific question, if you want code to run once at init-
time, override init(). If you want code to run once at shutdown time,
override destroy(). But you shouldn't need these, since the @Resource
annotation will cause the container to do the initialization for you.
... and don't forget to close() your connections, even if exceptions
were raised, otherwise you'll have a leak.

Hello,
after your post I would open/close my db within each service call.
If I would do it with a pool, I would need 2 entry points, one to open
the pool and one to close it. If I would go this way, would these
entry point exist (is there a deinit)?
Thanks

Hi Magnus.
Your server-side service implementation is a class that extends GWT's
RemoteServiceServlet, which itself extends the Servlet interface. If
you need to perform once-only initialization, you can do so by
overriding the init() method in your class.
Note, however, that init() is probably a bad place to open database
connections, as your backend will be accessed concurrently by many
users and multiple database connections are needed. You should
probably either open and close database connections inside the RPC
service calls themselves (using a database connection pool behind the
scenes), or in some scenarios store some resources in the user's HTTP
session (acquired by calling
this.getThreadLocalRequest().getSession()).
If you need more help, can you send more details about your
application?

Hi,
I wonder where to open and close the database on the server side, and
where to store the database connection.
At this point, I only have the server side implementation of my RPC

entry point like onServerLoad or something like that.
An alternative way would be to open and close the database on each
service call.
How do you do this?

[gwt-contrib] UiBinder tweaks for GWT Designer
To support UiBinder in GWT Designer we need to have several changes
in UiBinder generators, writer and parsers.
I will describe below these changes as they are done now.
In real patch I will group as much implementation details as
possible into single class like DesignTimeUtils or GWTDesignerSupport.
It will check for GWT Designer presence and do something only in this
case.
So, main question is following. Will GWT team accept patch with such
changes?
This would allow us avoid creating internal patches for 2.0 and each
future version of GWT.
1. Declare in binder implementation interface and field with it.
Something like this:
public static interface WBPObjectHandler {void handle(String
path, Object object);}
public WBPObjectHandler wbpObjectHandler;
In method createAndBindUi() directly after creating each Widget
instance (but before applying setX() methods) wbpObjectHandler is
used to notify GWT Designer about new widget and its path in XML. GWT
Designer bind Widget instance to model (using path) and also asks
default values for all properties using getX() methods.
Path in XML is / separated string of indexes.
For example in
ui:UiBinder
ui:style/
g:FlowPanel styleName={style.panel}
g:Button text=New Button/
/g:FlowPanel
/ui:UiBinder
0/1 is FlowPanel
0/1/0 is Button
2. Declare in binder implementation Map with values of attributes.
public final java.util.Map wbpAttributes = new
java.util.HashMap();
and fill it, here is example if code generated for ui.xml above
if (wbpObjectHandler != null) wbpObjectHandler.handle(0/1/0,
f_Button2);
f_Button2.setText(New Button);
wbpAttributes.put(0/1/0 text, New Button);
f_FlowPanel1.add(f_Button2);
if (wbpObjectHandler != null) wbpObjectHandler.handle(0/1,
f_FlowPanel1);
f_FlowPanel1.setStyleName( + style.panel() + );
GWT Designer needs to know attribute values to show them to user in
properties table. Not all properties have getter, so we can not get
these values for existing Widget object.
3. In special parsers for panels, remember also values of attributes
for artificial elements. For example Cell in CellPanelParser (and
Dock in DockPanel).
// Parse horizontal and vertical alignment attributes.
if (cellElem.hasAttribute(HALIGN_ATTR)) {
String value = cellElem.consumeAttribute(HALIGN_ATTR,
hAlignConstantType);
writer.addStatement(%1$s.setCellHorizontalAlignment(%2$s,
%3$s);,
fieldName, childFieldName, value);
//XXX Instantiations
writer.addStatement(wbpAttributes.put(\%s\, %s);,
widgetElem.getPath() + Cell. + HALIGN_ATTR, value);
//XXX Instantiations
}
4. To allow quick updates of design canvas as user changes properties,
without reloading GWT context each time, we should:
4.1. Generate Binder implementation class with new name each time, so
be able to define each time new class in same ClassLoader. Right now
we just add current time to the name of class.
//XXX Instantiations
// generate class with new name each time, to allow refresh in
same ClassLoader
implName += _wbp + System.currentTimeMillis();
//XXX Instantiations
4.2. To parse/render UI.XML file content without saving, i.e. from
memory/editor, generate should try to read document from memory.
Something like this:
private Document getW3cDoc(MortalLogger logger, String templatePath)
throws UnableToCompleteException {
//XXX Instantiations
{
String content = System.getProperty(wbp.gwt.UiBinder +
templatePath);
if (content != null) {
Document doc = null;
try {
doc = new
W3cDomHelper(logger.getTreeLogger()).documentFor(content);
} catch (SAXParseException e) {
logger.die(Error parsing XML (line + e.getLineNumber() +
):
+ e.getMessage() + + content, e);
} catch (Throwable e) {
logger.die(Error parsing XML + content, e);
}
return doc;
}
}
//XXX Instantiations
URL url =
UiBinderGenerator.class.getClassLoader().getResource(templatePath); //
this is default implementation

Re: [gwt-contrib] UiBinder tweaks for GWT Designer
Konstantin,
I've not gone over these proposals in great detail, but it does seem like a
reasonable idea to build design time hooks into UiBinder-generated code.
One very important caveat would be that it must be possible for the compiler
to strip them out completely in production mode (this seems likely, but we'd
have to be very careful to make sure it happens in practice).
I'm going to have to defer to Ray on the architectural details (I haven't
touched this generator in a while), and I suspect he'd want to make sure the
proposed mechanisms would be generally useful for other kinds of design
tools. He's on vacation this week, so I doubt he'll be able to look into it
until next week at the earliest.
@rjrjr: Please do have a look at this when you have a moment, and if you'd
like me to look at anything in particular, I'd be happy to.
Cheers,
joel.

Re: [gwt-contrib] Re: UiBinder. Code style for constant parsers.
Le 22 juin 2010 07:03, Konstantin.Scheglov konstantin.scheg...@gmail.com a écrit : Pretty much everything we've done so far has been limited to automatically exposing the Java-level APIs in all their ugliness. The h/v alignment values are implemented somewhat manually, but for things like enums I really like the idea that they can be exposed completely automatically. On the other hand, it would be nice to have prettier names. Perhaps we could find some sort of convention for exposing prettier names for [pseudo-]enums. What about a shortName() method on the enum itself? Hm... Yes, I think that it is possible to create some generic parser for enum-like constants. However because they are not real enums, following things come to mind: 1. During registration in AttributeParsers we will need to pass list of values; 2. To check for shortName() using reflection; 3. To test that each such constant parser instance works correctly, I would write special ui.xml file. Also one more thing worries me. Do you think that it is OK to add into GWT classes on this level information which is used only by some presentation of GWT? I mean that parsing ui.xml files is part of UiBinder, so it should be problem of UiBinder how to parse it. It *does* seem a little odd to have to add a UiBinder-specific short name to every enum (or enum-alike) used as a widget property (especially if they somehow end up in the compiled output). On the other hand, it would also kind of suck to have to put them in a completely separate place, which most widget authors would simply forget to do. On second thought, maybe we can actually get away with just convention. Most enums (e.g., Style.Unit) have names that are upper-case by convention, but we could allow UiBinder to specify them in a case-insensitive manner without ambiguity. That would leave only a handful of special cases (like the TextAlignmentParser patch you just sent). @rjrjr, konstantin: How does that sound to you both? -- http://groups.google.com/group/Google-Web-Toolkit-Contributors

But note that these characters are called out specifically in the ECMAScript 5 spec, section 15.12.2 (describing JSON.parse): JSON uses a more limited set of white space characters than WhiteSpace and allows Unicode code points U+2028 and U+2029 to directly appear in JSONString literals without using an escape sequence. What other characters do you have in mind? On 2010/06/23 18:54:37, jat wrote: Are you sure these are the only ones?

What other characters do you have in mind? Mostly other control characters. I would prefer to see the test actually generate strings with all these characters and verify that they come through ok. It doesn't have to be as thorough as the RPC unicode escaping test, but something along those lines would be better. http://gwt-code-reviews.appspot.com/659801/show -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
